"Hydrolysis Of Salts" Learning Difficulties Analysis And Teaching Strategies

“Hydrolysis of salts”belongs to “chemical reaction principle”in senior high school chemistry curriculum. This section is so complex and abstract that it brings some difficulties to teaching and learners understanding of learners.This paper describes the background of the problem, including description of the object, purpose and significance of this study. “Hydrolysis of salts” is an important part of chemistry in high school.and “Hydrolysis of salts” is also the difficulty in teaching.The paper then expounds learning difficulties and relevant researches of “Hydrolysis of salts”, including research of difficulties in learning, difficulties of chemistry learning, the application of difficulties in chemistry learning and the research of “Hydrolysis of salts”.Before the search of difficulties in learning of "Hydrolysis of Salts",we analysis the content of "Hydrolysis of Salts" in two aspects: criterion for curriculum and teaching materials,fixing the main conception and knowledge of "Hydrolysis of Salts".Then created a concept map for the concept of "Hydrolysis of Salts".Based on this I made the questionnaires, and explained the reliability and validity of the questionnaire.The sample is students in six classes of high school.Based on the above analysis, the paper also discussed the teaching strategies, mainly including concept map, finishing strategy, multiple representation strategy.
